I thought it would be awesome to get yourself maybe a bigger pet creature (for example hl2 combine hunter) which you could ride to get from point {A} to point {B}.

How it would work? Basically, like a vehicle with the particular npc model and it's animations for strafing movement and maybe attacking animations.

How it would look? Player model would be somehow attached to the upper side of the npc's body (I don't if possible. I'm not any scripter.) And it would stick there until player decides that he wants to walk.

So tell me what you think? Is it possible? Would it fit to the gamemode?

I myself hope that this could be made, if not to the gamemode. Maybe to gmod otherwise.
